I thought the idea was to build a recipe for your device that could create the software complete with all the pieces. Certainly, having a list of packages that you need to install
via zypper is fine, but I thought that not the concept behind Yocto???
Sorry for the dumb questions.
It's actually a combination of both worlds - you can use existing recipes
to add functionality by just including those packages in your system, either
at initial build time or by using the packaging tools. You can also easily
write your own recipes to build specialized packages. The combination is
up to you.
So if I wanted to build Firefox into my Yocto project. How is that done??

A point of terminology - recipes are used to construct packages which can
then be installed, etc. They are functional units, not necessarily tied
to any particular device or system.

n.b. top posting on mailing lists makes your replies harder to follow :-(

I approach embedded Linux from a path of taking a Distro like Ubuntu or Fedora and chopping it down to a working set of code that forms the final solution. Obviously, not
the same
methology as Yocto. With some success with the current methods, it's difficult to see the advantages of Yocto. I'm reading what I can find to get smarting on Yocto, but
like most
new concepts, you try to compare what you used to do with how to do it with the new concept.
For example, if I use a distro, I can install packages really simply with yum or apt-get; update them the same way. If I start with a Yocto meta-??? that's closest to my
solution, and get it working at a base level, how do I add things, like browsers, or other application?

Using very similar tools - zypper is just like yum, or if
you choose to use ipk packages, opkg
